Background technology
Ceramic filter adopts capillary ceramic plate as filter medium, the application air-locked capillary effect principle of microporous permeable and the solid-liquid separating equipment that designs, have efficient, energy-conservation, filtrate is limpid and water resource makes full use of, automaticity high.Along with natural resources is day by day in short supply, concentrate grinds refinement further, and ceramic filter plate blockage of the micro orifice problem is more outstanding, becomes one of principal element of restriction ceramic filter production capacity.
Therefore, solve ceramic wafer blocking, recover the important channel that its power of regeneration becomes raising ceramic filter production capacity.Chemistry and physical mixed ablution are methods conventional at present, Chemical cleaning selects suitable cleaning agent for different filter materials, and chemical and the fine grained be blocked in ceramic wafer carry out chemical reaction, reach the object of micronized particles, again in conjunction with circulation backwash, fine grained is gone out.Conventional Chemical cleaning mainly contains simple pickling, oxidation pickling, oxalic acid cleaning and caustic dip etc., no matter be that Chemical cleaning all can relate to chemical agent and rinse water consumption, problem such as cleaning treating waste liquid and discharge etc.
And at present, method of operating method is, by dispensation apparatus, cleaning fluid is delivered to ceramic wafer inside, backwash water is coordinated to clean; In cleaning process, the cleaning fluid in groove flows in kiln basin by slip overflow pipe, dilution slip; Cleaning terminates directly the cleaning fluid in groove entered kiln basin or directly drain afterwards.Like this, just cause the waste of chemical agent and water resource, and the pollution of environment; Meanwhile, overflow and the cleaning fluid be discharged in kiln basin can dilute even contaminated material, affect equipment capacity.
Summary of the invention
The object of this invention is to provide a kind of new cleaning method and device, realize ceramic filter cleaning fluid and recycle, reduce chemical agent and rinse water consumption, reduce production cost and soiling solution control expense; Pollute slip when avoiding cleaning fluid to enter slip, reduce material concentration, and then affect filter production capacity; Reduce discharging of waste liquid, reduce environmental.
Object of the present invention is achieved through the following technical solutions:
Cleaning method, comprises the following steps when first wash:
A) rinsed well by the parts clear water comprising ceramic filter plate in cell body, the sewage after flushing is emitted by the blow-off valve bottom cell body;
B) add clear water again to the ceramic filter plate in submergence cell body, use ultrasonic wave to carry out physical cleaning to ceramic filter plate;
C) then to ceramic filter plate use chemical medicinal liquid carry out chemical backwash, make the wash liquid stream overflowed in washing lotion pond during chemical backwash, after chemical backwash completes by the cleaning fluid discharge of the retention in cell body in washing lotion pond;
D) finally use water purification backwash is carried out to ceramic filter plate, make the wash liquid stream overflowed in washing lotion pond during backwash, after backwash completes by the cleaning fluid discharge of the retention in cell body in washing lotion pond;
Wash beginning from second time, replace the clear water in above-mentioned a) and b) step with the cleaning fluid in washing lotion pond.
Realize the device of preceding method, comprise the cell body 1 ceramic filter plate 2 and ultrasonic oscillator box 3 being housed its inside, the clear water pipeline 4 that can inject liquid to cell body 1 and washing lotion water lines 5, in cell body 1, get rid of material drain line 17 with the marker pipe of blow-off valve 20, the dispensation apparatus 6 be connected with ceramic filter plate 2 inside and backwashing system 7, washing lotion pond 13, it is characterized in that one end of described washing lotion water lines 5 is connected with washing lotion pond 13 by circulating pump 12, the other end is opened on the top of cell body 1; One end of described drain line 17 is connected with washing lotion pond 13, and the other end is connected with top with the bottom of overflow valve 18 with cell body 1 respectively by underflow valve 19.
Further, described dispensation apparatus 6 comprises for storing the storage tank 15 of cleaning agent and medicament being delivered to the measuring pump 16 of ceramic filter plate 2 inside; Described backwashing system 7 comprises to be sent into ceramic filter plate 2 inside for water purification and provides the backwashing pump 11 of pressure, controls the backwash valve 10 of backwash water break-make, makes the water entering ceramic filter plate 2 inside be the filter 9 of water purification; Dispensation apparatus 6 converges with the outlet of backwashing system 7 and is connected with ceramic filter plate 2 inside after becoming backwash pipeline 21 again.
Further, the bottom in described washing lotion pond 13 is connected with blowoff valve 14.
Again further, described backwashing system 7 also comprises one and is used for showing the Pressure gauge 8 entering the ceramic backwash water pressure crossed in filter 2.
Compared with the prior art the present invention has following good effect: can reduce by the rinse water consumption of more than 60%, extends ceramic wafer service life, increases filter production capacity; Reduce consumption of chemical agent, reduce production cost; Soiling solution discharge capacity is little, energy-conserving and environment-protective.
